Get hold of lsdrv, and see what that tells you. (Look at the raid wiki for details.) I don't know if it will have endian issues, but if it doesn't an expert will probably be able to chime straight in and tell you the create command.

The other thing is, read up on overlays because, if you overlay those disks, you will be able to "create" without actually writing to the disks. That way you can test - and even do a complete backup and recovery - without ever actually writing to, and altering, the original disks.
